Seiko GMT Coke

Words can’t describe how happy I am with the end product. I contacted KoolMods around 3-4 weeks ago and spoke with Riley. I told him I was interested in a custom watch based off the 2004 Rolex GMT “Coke”. Riley was very helpful throughout the whole process by sending me photos of all the different materials , looms, bezels, glass type and bracelet type to ensure what I was asking for was 100% correct. I revived my watch very quickly and am blown away by the quality I have received. 10/10 would recommend for anyone interested in designing their own Seiko Custom watch.

Seiko GMT Neo Vintage Dial Black Bezel

My first impressions are very positive, this is a vintage style that I have loved for a long time. I like the slight Sun ray on the dial to make it unique, the combination of clean maxi stle hour markers combines the modern and vintage gmt style very well. I also like the sizing a lot, I tend to lean to 40mm or less so this hits the spot.
